Glassine sleeves are used for storing stamps, photographs, acrylic paintings, moth and butterfly wings, negatives, slides, small irreplaceable books, important documents, and other materials that can be damaged by the outside elements including air, moisture, dust, oils from our skin, scratches and exposure to direct sunlight. Glassine is a very lightweight, waxy finished, opaque paper material that has no acids or chemicals in it and is made from paper pulp. These acids and chemicals that are used in most storage sleeves and envelopes over time can harm or destroy the item being stored inside the sleeve. Glassine sleeves come in a range of different shapes and sizes, so no matter how big or how small the sensitive object is that you need to store, you'll be able to find the correct size sleeve for the job. These sleeves are open ended, and you can either just fold the edge over to close them, or you can also purchase a special glassine adhesive that will provide a more secure seal (that also allows you to re-open the sleeve when needed). Here are some more perks about using glassine sleeves. Besides being able to store valuable irreplaceable items and know that they won't be damaged by exterior forces, another important factor is that they are in an everyday persons price range, so no matter how much money you have or don't have, you can know that your personal priceless items that are very important to you, will be intact and unharmed, and leave you with the peace of mind that they will be in the same condition the next time you go to get them. With many companies that sell glassine sleeves you can choose from an array of colors, but most people that decide to use this product like to utilize the semi-opaque option so that way they can see exactly what is being stored inside of each sleeve.
